Modeling and simulation of musculoskeletal system of human lower limb based on tensegrity structure, 2019
Topics: Tensegrity structure; lower limb model; motion analysis; gait simulation
Authors: Zhanxi Wang , Chaoran Yang, Kang Feng and Xiansheng Qin
In this paper, a mechanical model of the skeletal muscle of human lower limb system is established by using the Hill muscle model and kinetic equation of the movement of lower extremities according to the attachment positions of skeletal muscle. State vector and neural control are delineated by the direct configuration method. Changes of gait and skeletal muscle stress during walking process are analyzed with energy consumption as objective function. Results illustrate that simulation data are in good agreement with actual walking gait data. Feasibility and correctness of the designed model and control behavior of skeletal muscle tension structure are also verified.

What is fascia and in what way does fascia change the whole way of looking at the body?
Fascia is a network of connective tissue, without beginning and end, which encloses everything in the whole body, from muscles and bones, to organs and cells. But what does that mean?
Why do so many female football players suffer from cruciate ligament injuries?
A lot of injuries after a long break might not be that unusual – but why do so many female athletes suffer from cruciate ligament injuries?

To understand Fascia we need to cross the bridge & see things from another perspective
Exclusive interview with Gil Headly explaining how Fascia changes the perspective on how we look at the body at the 2015 Fascia Research Congress in Washington DC.
How do we learn to understand Fascia?
Fascia is a new perspective, a completely new way of looking at the body, a new way of conducting research and a new way of understanding the world. So how do you learn to understand Fascia?
Fascia in Horses – Danish veterinary exploring uncharted territory
In 2015 veterinary Vibeke S Elbrønd published the first report on Fascia and horses. Through autopsy she found that the horse has the same kind of chains and networks of connective tissue through the body, as found in humans.
Fascia does not only envelope the whole body, it turns the way we look at the body upside down
At the 2015 Fascia Research Congress in Washington DC, Tom Myers, the author of Anatomy Trains, gives a short introduction to Fascia and how new research changes the way we look at pain and discomfort.
Can you heal osteoarthritis?
The function of the articular cartilage is to reduce friction between the two articular cartilage surfaces and facilitate sliding when the joint moves, and to absorb the load when the joint is exposed to pressure, compression
Fascia Lines are the intersections of the body
The concept of Fascia Lines is a great way to understand how the body functions and how treatment can be optimized to increase mobility and functionality. The main principle is that muscles, no matter what they do individually, also affect tissues throughout the entire body.
